This invention relates to airfreshening, sweetening, .neutralizing, perfuming, sterilizing, mothproofing, or otherwise treating devices commonly known as deodorizing devices.

More particularly stated, this invention relates to deodorizingdevices of the air circulating type. In this type the air to be deodorizedthat is, freshened, sweetened, neutralized, perfumed, sterilized, .rnoth-proofed, or otherwise treatedis mechanically circulated in the room being deodorized.

It is the object of this invention to provide a deodorizing device of the air circulating type which will be comparatively simple in structure, cheap .to manufacture, easy to install, and easy to .service.

I achieve the foregoing, as well as other objects, by placing in a container having air circulating apertures a unit consisting of a sealedin-oil motor to which is operatively connected an air propeller near which is positioned the composition for freshening, sweetening, neutralizing, perfuming, sterilizing, moth-proofing, or otherwise treating the air. Said composition for treating the air isherein broadly designated as a deodorizing composition.

For the purpose of describing my invention with the particularity required by law I have shown in the drawings which form a part hereof and will now describe several embodiments of my novel concept.

.In said drawings Fig. 1 is a side View of my novel deodorizing unit with the casing and wall attaching bracket in section in order to show otherwise hidden parts.

Fig.2 is. asecticn in the line 22 .of'Fig. 1.

Fig.3 is a top view .of the unit shown in Fig. .1.

Fi 4 is a bottom view of the limit shown .in Fig. 1.

Fig. '5 is an enlarged vertical section, taken similarly to Fig. 1, of a fragment of a modification of the casing shown in said figure. The fragment shown is :at the junction point of the two casing sections.

Fig. 6 is a side view of a modification of the deodorizing element carrying bracket and deodorizing element receiving shaft shown in Fig. 1.

Referrin more particularly 'to the drawings, wherein similar reference numerals denote similarparts, referencenumeral I designates my de- '0 dorizing device'as a 'unit.

The deodorizing device I consists of an outer casing 2, a motor and fan and deodorizing element carrying bracket 3 carried by said casing 2, amotor and fan unit l and a deodorizing element 5 carried by said bracket 3, and a wall attaching'bracket 6 attached to said casing 2.

The casing 2 consists of two sections I and 3. It may be made of any suitable material. In the embodiment here shown said casing '2 is made of cellulose acetate plastic.

The casing section 1 .has formed therein the louvers 9 and the circular opening 49. The casing section 1 terminates. in an annular lip 19 bounded by a shoulder l I.

The casing section 8 has formed therein the louvers l2 and terminates in an annular lip l3 boundedby a shoulder M. The casing section 8 has formed therein a pluralityof suitable apertures through which extend the rivets 15 which simultaneously attach both the motor and fan and deodorizing element carrying bracket 3 and the wall attaching bracket 6 to said casing .section 8.

The motor and fan and deodorizing element carrying bracket 3 consists of the arms l6, [7, I8, I 9, 2O and2l which combine to form a substantially inverse U-shaped member and a ring 22 carried by the arms [6 and 21. The ring 22 has formed therein suitable apertures through which extend the screws 23 which anchor the motor 32 of said motor and air propeller ,unit l to said ring 22. The arms [8 and 19 have formed therein suitable registering apertures through which extends the deodorizing element receiving shaft .24.

The deodorizing element receiving shaft 24 is threaded at both its lower and upper ends 25 and 26 respectively. The lower end 25 of said deodorizing element receiving shaft 24 has mounted thereon the spaced nuts 21 and 28 which serve to unite the arms l8 and I9, attach the deodorizing element receiving shaft 24 to said arms, and to space the deodorizing element 5 from said arms l8 and 19. The upper end 26 of said deodorizing element receiving shaft 24 has mounted thereon the nut '29 which serves to press the casing section 1 toward and into contact with the casing section 8. The deodorizing element receiving shaft 24 extends through a suitable aperture 30 in the center of the deodorizing element 5 and has positioned thereon above said element the washer clip or spring collar 3| which retains the deodorizing element 5 upon said deodorizing element receiving shaft 24.

The motor and air propelling :unit 4 consists of a sealed-in-oil-motor 32 which has attached thereto a suitable shaft 33 to which is attached the fan or air propeller 34. ,It also has attached thereto a suitable conducting wire 41 terminating in .a plug '48 for connection to a source of power.

The deodorizing element 5 consists of a porous block containing a composition which will freshen, sweeten, "neutralize, perfume, sterilize, moth-proof, or otherwise treat the .air. "The porous block Lhere shown'is made of ceramicmater'ial. It maybe made of any other material having the necessary porosity and which will not be adversely affected by and will not adversely affect the deodorizing composition.

The deodorizing composition is introduced into the porous block in any suitable manner. I have done so b placing the block in a solution containing the deodorizing composition and also by forcing the composition into the block by pressure. In both cases the porous block became substantially saturated with the deodorizing composition.

The air to be deodorized enters the unit through the louvers 9 as indicated by the arrows A and leaves the unit through the louvers I2 as indicated by the arrows B.

The casing 40 shown in Fig. differs from the casing 2 shown in Figs. 1 to 4 only in the fact that the upper casing section 4| has an annular channel 44 formed at its lower edge 43 which receives the annular lip 46 bordering the shoulder 45 of the casing section 42.

The motor and fan and deodorizing element carrying bracket 59 shown in Fig. 6 differ from that shown in Figs. 1 to 4 only in the fact that a continuous arm 5! has been substituted for the two arms 18 and 19.

The deodorizing element receiving shaft 60 shown in Fig. 6 differs from that shown in Figs. 1 to 4 in the following particulars:

(1) It terminates in a head 8| at its lower end and is threaded for its entire length.

(2) A wing nut 62 has been substituted for the washer clip or spring collar 3 I.

My novel deodorizing unit may be mounted at any desired point in a chamber by suitable means such as the screws 35 which extend through suitable apertures in the wall attaching bracket 6 into the wall 36 or any other object in said chamber which has been picked as the supporting member for said deodorizing unit.
